So, to recap:
What's on the edge of being confirmed or deconfirmed:
-(Possibly) three scenarios, with Nero's taking place first chronologically, with 10 missions each.
-V using Statues of Time.
-V's music being orchestral rock. (Which we do know is one of the genres the game draws from, as the Cavalier Angelo fight shows. Rock + Violins is a thing in the game, but we don't know if V's theme has the same motif.)
-V's weapon and gameplay style revolving around summoning.
The three scenarios seems to be a thing though. I kinda hoped we would learn more about V (both for DMC5 and Smash leak perspective), but even if we don't know anything regarding his gameplay his "crow" seems to point toward a possible summoning skill of some sort. I wouldn't be surprise if he doesn't actually get an orchestral rock as music theme, maybe their plans for the soundtrack changed over time, but after the debacle that was the Subhuman song they may change it to some more traditional fare at the last minute.
Will not know until launch, most likely:
-Vergil not in base game as a playable character.
-Nero using Yamato again (it was stored in the arm that got ripped off in the E3 trailer, so maybe.)
-V giving a different answer for his name each time.
-DMC4:SE on Switch, Xbox One, and PS4 with a physical release.
-Final missions being able to play as any of them.
-Alternate costumes.
Almost any of these will need the game to be released in order to be confirmed/deconfirmed, sadly. Physical releases for DMC4:SE are not a lock, remember the leaker just said "expect". Altough, if Dante is really in Smash, Capcom may wait until he's actually revealed before announcing the Switch version, otherwise they could spoil the surprise.
Not mentioned:
-V's book
-V's crow friend
-Plot details
-Network multiplayer (confirmed on every store, may just not have known about it.)
He never said he knew everything about the game, the more I reread his post the more it sound like an intern who stumbled in the editing room. Network multiplayer seems interesting though.
Unable to be confirmed:
-Vergil was scrapped for MvCI
This is actually an interesting bit, problem is we will never be able to confirm it. We may ask to Vergeben, but even if we manage to get a positive answer from him we still won't have an actual proof, just his word.
Wrong:
-Dante's theme being Shootie HG (though, this might actually come true after the fact, solely because Shootie is actually trying to get a hold of the people working on DMC5 to do Dante's theme, so this might end up being retroactively true, though it certainly wasn't planned.).
One thing he got undeniably wrong. So out of 12 statements, he got 1 wrong, 1 we cannot confirm/deny, 4 totally right, 1 half right (about V looks, but the summoning part still need confirmation) and 5 still in the dark, Smash trailer included. Which lead me to...
The next big trade show/place where they might show stuff off is Paris Games Week, in October. I doubt Playstation Experience in December is going to have anything on it, as Microsoft is paying for the marketing. The Game Awards in December might also have something on it.
I highly doubt they will show something interesting there, maybe some more gameplay but that's about it. So, whats seems to be the general opinion about the DMC5 leaker here? As Aeon Lupin said:
I do think this guy has some connections and info for DMC5. The thing is he could've very likely added the Dante for Smash bit just to give himself more attention.
I'm still on my "loz18 strategy" idea, the leaker really had DMC5 info and made up Smash related stuff, but rather that doing for attention he did for pushing his favourite character chances to be in Smash (at least for DLC). What do you guys think? Full legit? Full Fraud? Half and half?
